Once you have added the appropriate Web items and formatted them as needed, you then can move into the properties of the Web items and make the necessary adjustments in this area also. When you insert additional Web items using Insert | Web Item, pay attention to where you position the cursor in your Web template. The cursor position determines where the new Web item is inserted. When you insert Web items using drag and drop, the position of the cursor is irrelevant. Make sure that you set the data binding and any Webitem-specific parameter settings for the correct Web item. To make settings for a Web item, select the Web item in the Layout view. In the header of the Properties window, the system displays the Web item for which you can change the settings. As an alternative to selecting the individual Web items, you can use the dropdown box to toggle between the attributes of individual Web items. Once you ve completed these activities, you can save your Web application.

The last load context we will discuss is the load without a context. This context is reserved for assemblies that, generally speaking, do not have a load context period. Examples of such assemblies are those assemblies generated using the Reflection namespace and Emit APIs. In these cases, the CLR does not do any type of probing. The exception to the rule is when applying identity to a generated assembly using policy. In this case, if an assembly is located in the GAC, it will be used. At this point, we have discussed assembly identity, the Global Assembly Cache, and the different load contexts that are available. Many subtle and interesting problems can occur when loading assemblies (especially when mixing load contexts). In the remaining part of this chapter, we will take a look at some real-world examples of problems and how the available tools, instrumentation, and debuggers can be used to get to the bottom of the problem.

Illustration. Here, you can see information about the selected data provider, including the key date, the age of the data, the time of the last change, the person who last changed the query, and the date of the last refresh. This is critical information for the business user, who needs to know the last time data was refreshed or the actual report was changed. You also receive information about which static and dynamic filter values the query has and the variable values with which the query is filled. If needed, any of this information can easily be displayed directly on the report, though you need to use some of the functionality within the WAD to do so, which will be discussed in 4.

After setting up and reloading the symbols, we utilize the X (examine symbols) command to display all symbols that contain SaveFile . It turns out that one of the symbols matches perfectly and also happens to be a function. Then, we use the bp command to set the breakpoint on that function (alternatively, we could have used the

As indicated in Table 1-6, the Properties context menu option requires further discussion. As previously mentioned, some functions are found in many areas, but the Properties options are unique in some ways. Properties can be accessed via the context menu either from the navigation pane (navigational filter) or from the analysis grid (body of the query). With your cursor on either the characteristic or the characteristic value, rightclick and choose Properties from the context menu. The Properties attributes are the same parameters from either of these areas characteristic or characteristic value. Table 1-7 lists and describes the fields and the options to fill those fields, and the results that you would view in the query. The following illustration shows the initial screen of the Properties dialog box for the characteristic Sold-to Party. In addition to these parameters, you also have an icon at the very bottom of the screen to turn on the technical names for the objects.
